So it looks like the problem is merely in allocating enough length for the result string. ------------------------------------------------------------------------ [2017-01-06 20:24:18] kulakov74 at yandex dot ru Yes, thank you, but in this particular case it doesn't matter - everything works the same way with "\\". And sorry, I didn't make it quite clear: in my case, the directory is NOT a link, so readlink() should return the dir, not a target, but it DOESN'T, so my script thinks it IS A LINK. So no mklink command had been used. I use ini_set('default_charset', 'UTF-8'); and then I get the dir from opendir()/readdir(), so it should be UTF-8. ------------------------------------------------------------------------ [2017-01-06 19:51:08] ab@php.net Thanks for the report. Double quotes will lead to the backslash extrapolation, backslash need to be escaped therefore. Need also to know, what kind of link is that? Also - is the string passed UTF-8 encoded? Could you provide maybe an exact mklink command or alike, to get the reproducer? I've just tried with a junction and see no issue. Thanks. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
